Patented April 2o, 1909.

Application led May 14, 1908. Serial No. 432,92'9- Be it known that I, HERMANN SCHRDER, a citizen-of the United States, residing at New York, in thevcounty of New York and State lof.New York, have invented certain new and useful Improvementsv inl Phonographs, of which the following is a specificatlon.

This invention comprehends certain new and useful improvements in sound reproducing or talking machines, and the invention has for its object an improved construcf tion of graphophone of that type in which the megaphone or horn is dispensed with, and in which the sound reproducing and amplifyingmeans' are inclos'ed within a case or cabinet. vAnd 'a further object of the ineinbodies a novel and ad vant ageous con struction and arrangement of parts whereby the sound may be intensified and mellowed or sweetened, and characterized by ahih degree of resonance, avoiding any of t e harsh, metallic effects 'which are incidental to the ordinary graphophon.

With theseand other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions', arrangements and combinaully describe and then point out the novel features of construction in the appended For a full understanding of the invention, reference is to be had to the following description and accompanying drawings in which: A'

Figure 1 is a lon itudinals'ectional view on the line 'y-Jj of' ig. 2 of a talking machine embodying the improvements ofl my invention; Fig. 2 is a horizontal sectional view thereof on the line of Fig. 1- Fig. 3 is' a detail sectional 'view and side elevation of the sound arm; Fig. 4 is a detail transverse section through the support for lthe sound arm. .F.igs. 5 and 6 are detail pertafry sectional view of a modiedform OGheinstrument. Fig. 8 is a detail sectional View detail sectional xfiew of a modified forin of 0`l1`1dI1IL 'Corresponding and like "arts are 'referred to in the descrip 1011 and indicated' strings 14 refer-ably 'extend arcuri in all the views of the drawings by the saine reference characters. i The 'case or cabinet of 'my iin rove'd graph phone embodies a bottom 1, Va ack 2, a top 3 having a hin ed lid or cover 4 that may be held in raise position by means of,

slotted'members 5 engaging thestuds '6, and a front 7 through which the sound is emitted and which is provided with a hinged door `8 preferably provided with one or more shutters 9 designed 'to regulate or control the volume of sound. l i

The' cabinet is divided by a horizontal partition l0 into lower and upper 'compartments, the motor case 11 'being located in the lower compartment, `while the other partsof the apparatus are' supported by and on the. partition or platform 1o in the ripper compartment,

'12 designates the turn tabl'efor the record disk.

.means-of the present invention inclu sound-board islwhieli is suportedu the platform 1o within the ea inet at 'tje rear The sound 'm'ello'wiing and i end thereof and which may be of deine by being passed through openings formed in bars 15 secured at their upper and lower ends within the sound board and vertically dis-V posed therein, the said strings being held position by tuning pegs' 16 moonted on corresponding bar's 17 at or near theends of. the

'sound-board. Within the dome shaped sound-board 13 is a bell 18 which isshaped as the ,segment of a spherepand which is supported in an elevated position spaced from the inner Wall of the sound-board b" being supported upon the up er end of a racket 19, the lower end of the racket being secured byl screws or thelike to the platform 10.

' j The spend wavessre intended vto be direcited against the bell 18 and the sound; heard 13, or againsttlre latteronly if the bell is not used, by ineens of a sound erizo peints rearvrardlas shown, the: rear ico A end of said sound arri Being prefereer eared 1 1 c so 40 designates y"c movement of the member 35 or bell shaped and being preferably vprovided with a damper 21 in the form of a disk pivotally mounted ,within the sound arm and capable of being adjusted by means of a -25 designates a set screw which passes through the ring 23' and isdesigned to impinge against the sound arm and hold it if desired, relativelyy stationary as against this pivotal movement, and at any desired inclination. The ring 23 is mounted on the upper end of a vertically disposed shaft 26 which is designed to be turnedl by a self feed apparatus (not shown) operatively connected to the motor so as to swing the sound 25 arm laterally over the upper face of the re'cord disk as the turn table 12 ,rotates The shaft 26 is mounted within a hollow post Y 27 which extends upwardly from and whichis secured at its base to 'the platform 10 between the turn table 12 and the sound board 13.. l.

28 designates a snap spring which is secured tothe sound arm 20 andl which is adapted to spring* into vengagement with a lug or catch 29 on the ring 23 so as to hold the outer or forward end of the soundV arm in an elevated position whenever desired, to

insert a stylus in the sound box 30 or to re-V move a stylus therefrom. i The sound box 30 is secured in any desired manner to the outer end of an elbow which in one embodiment of the invention comprises an outer section 31 and an inner section 32 detachably connected together. The outer section 31 is formed at its inner end with' two inwardly rejecting pins 33 designed to slide inwar ly in longitudinal grooves 34 formed in the outer end of the member 35 of section 32 so as to properly 5o direct the section 31 to its place as it is slipped over the member 35. After these parts have been slipped one'over the other, they are secured together by means of a thumb screw 36 as shown. The section 32 of the elbow comprises thehinged section 35 and the relatively stationary section 37 to which the section 35 may, if desired,be

|rigidly connected at will by means of a snap spring 38 engaging the catch or lug 39.

an extension -which is formed on the hinged member 35 and which f is ada ad to at Within the member 37 of are hinge section 32 so as to prevent the escape of the sound waves during theindependent The member 37 of the section 32 is formed with a flange 41 by which the elbow may be secured by screws or other fastening means. to the outer end of the sound arm 20. f

In the practical o eration the set screw 25 '7 may be disengagedrom its contact with the sound arm 20 so as to ermit the entire arm tohave a" free vertica movement together with the sound box carrying elbow in which event the spring 38 is engaged with the catch v5 39, or if desired, the set screw25 may be ap# plied so as to hold the sound arm 2O at the desired adjustment in the ring 23 and the snap spring 38 disengaged from the catch 39 so as to permit the elbow alone-to move se freely vertically as the arm, elbow and sound box are swunglaterally over the upper surface of the record disk as the latter rotates. The sound waves passing" through the sound arm 2() 'will be directed into the S5 sound board -13 and also against the bell 18,

if the bell be used, said waves being therebyv amplified and passing outwardly in increased volume through vthe front of the cabinet. The sound board 13 and bell l18will,how-A 90 ever, either separately or jointly increase resonance of the`sound waves andff'thefv vin soundv waves will ,be mellowed therebyras' well as by the sympathetic strings le which will be set to vibrating. f' 953 If desired, the bell 18a may be secured difv rectly to the rear end of the sound arm 20L",` n in spiaced relation thereto as by means of brac ets 42, as illustrated in Fig. 9 'So as to move with the sound arm. Or, if desired, the sound board may be constructed as i1lus`- trated in Figs. 7 and 8 wherein 13a designat-es the sound board as regularly curved around the rear end of the' cabinet and 18b the bell secured directly to the sound-board, the sound waves being'brought into the bell by means of the taper arms 20h.l
